Amy Mahon

Simpson Thacher

As one of the star lawyers in the infrastructure and private equity space, Amy Mahon’s move from Clifford Chance to Simpson Thacher & Bartlett has gone swimmingly for her, winning instructions as soon as she stepped through the door of her new firm and throughout 2019.

Mahon brought one of her main clients, EQT, to her new firm and did her first deal at Simpson Thacher’s London office for the private equity house: the sale of GB Railfreight to Infracapital. She had previously worked on the acquisition of GB Railfreight by EQT back in 2016.

Some of Simpson Thacher’s institutional clients also fit in well with Mahon’s expertise. She acted on KKR’s acquisition of a majority stake in Hyperoptic, a fibre-to-the-building internet provider, and the sale of a 50 per cent stake in Spanish solar projects developer X-Elio by KKR to Brookfield Asset Management for $500m (£295m).
